Greetings hackers...

I have an interesting little problem.   I have about 13 customers that are 
running FreeBSD 4.5 to 4.7 (STABLE), with
3-port LinkSys print servers.

Everything seems to be working fine.  For the past 3 months one of these 
customers was reporting printing problems
on one of their printers connected to the print server.  The other printers 
are working just fine.  This particular printer is
a high load printer, printing about 50 to 70 pages at a 
time.  Occasionally, the printer just stops while printing.

We have to force a 'lpc restart lsjd1p2' command several times to get the 
printer to restart again.

Since it was only happening to one of the 13 sites, I attributed the 
problem to hardware... (cable, print server, printer, etc).

We have since changed out print servers, printers, cables and everything I 
could think of, all to no avail... The printer still
stops right in the middle of a print job.


Just now, another customer has reported the exact same problem.  They had a 
local hard ware tech come out
and he updated firmware on the print server, installed a new print server, 
switched out printers, and replaced cables
(both network and parallel).  Nothing has changed... The printer still 
stops while printing large print jobs.

I believe that lpr/lpd is not resetting after receiving a Busy/Ready (or 
Nack/Ack) signal.

Has anyone else seen this problem before?

Thanks in advance...

Peter Elsner

I worry about my child and the Internet all the time, even though she's
too young to have logged on yet. Here's what I worry about. I worry
that 10 or 15 years from now, she will come to me and say "Daddy, where
were you when they took freedom of the press away from the Internet?"
